Specification of Letters Patent.

Application filed June 20, 1917. Serial No. 175,886.

To all whom t may concern.'

Be it known that I, THOMAS E. MILLEs, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Copy-Holders, of which the following is a specification.

This invention relates to a copy holder, the primary object of which is to hold various kinds of copy directly in front of the operator and in which the parts are so constructed and associated as to provide a positive feed of the copy, causing each line to appear in consecutive order above an indicator. Y

An object of the invention is to provide a copy holder capable of supporting a heavy bound book as well as one or more sheets or a stenographers notebook.

Besides the above my invention is distinguished in the manner of associating the parts so that the same may be readily folded and capable of moving down with the typewriter when the typewriter desk is closed.

With these and other objects in view the invention will be better understood from the following detail description taken in connection with the accompanying drawings wherein Figure 1 is ka front elevation of the device with the curtains removed.

Fig. 2 is an enlarged view of the base portion.

Fig. 3 isa cross sectional view.

Fig. 4 is a vhorizontal sectional view.

Figs. 5 and 6 are sectional views through y the feed mechanism.

Figs. 7 vvand 8 are detail views of the coni,

necting plate.

Figs. 9A and 10 are detail views illustrating the use of the book support and brackets.

Figs. 11 and 12 are detail views of the regulator.

Figs. 13, 1/1 and 15 are detail views of the marker. l

v Fig. 16 isa perspective view of the clip.

Fig. 17 is a detailed view. Fig. 18 is a diagrammatic view illustrating the manner in whichthe flexible hands are connected to the rollers.

Again referring to the drawings the numeral 1. designates a base including ears 2, to which are lpivotally connected certain links of a group of pivotally connected links 3 forming va frame F, that may be extended l the base.

or contracted. Other of the links support shafts it upon which are journaled rollers 5 that in turn move upon tracks 6 carried by These shafts 4; also have mounted thereon spools 7 while a third spool 8 is journaled on a shaft 9 supported in the ears 2 and which forms the pivot for the adjacent links of the frame.

Connected to the spools 7 are flexible elcments in the form of steel bands 10 passing to, and wrapped around the drum l1 that forms one element of the feed mechanism 12 mounted in the house 13. One of the bands passes around the spool 8 before being connected to the spool 7, with the result that pull upon both bands will move the rollers toward each other for the purpose of extending the frame, and vice versa when the bands are released. When pressure upon the bands is removed and the frame is collapsed the shock created thereby is absorbed by the spring 14, passed under the spool 8 and connected to the spools 7. The movement of the frame toward its intermediate collapsed position is limited by the stop device 15 shown in this particular instance as consisting of a Y.

strip 16 having a central portion riveted to the base as illustrated at 17 while its end portions are arranged to form shoes 18 adapted to engage the spools 7 when the shoes are moved into the path ofmovement of the spools by the trip 19. The resiliency of the strip 16 tends to move the shoes out of the path of movement of the spools so that the frame may be finally collapsed such as when the typewriter desk is to be closed.

This trip device 19 consists of a manually operated rod 20 pivotally connected to arms 21 that are in turn pivotally connected to the shoes in sucha manner that when the arms 21 are in operative position they will lie in alinement with the direction of travel of the shoes when assuming an inactive position. It is of course to be understood that other devices may be used for limiting the movement of the rollers and the construction illustrated is only shown in a diagrammatic manner.

The upper portion of the frame F has certain of its links pivotally connected to a supporting member 22 while other links support rollers 23 that bear upon the under surface of the member 22 so as to reduce friction and distribute the thrust of the frame. This member 22 supports a clamp una 24 resiliently held in engagement with the vmember 22 by the resilient tongues 25 engaging an extension 26 on the clamp 24. This clamp 24 is used when the holder supports sheets or other thin articles while brackets 27 are provided for supporting books or other relative thick articles. These brackets are substantially Z-shaped formation with one end portion embracing the member 22 while the other end portion is arranged to engage the book.

Also supported by the base is a marker 28 consisting of pivotally connected arms 29 directly pivoted to t-he base, with the result that the marker may be folded in a compact position. The arms 29 support a rod 30 upon which is swingingly mounted a pair of strips or plates 31 with the result that one plate may swing independent of the other so as to compensate for the difference in thickness of a book when unfolded, that is to say, should the number of pages in one portion of the book when open, be greater thanY the other portion, the plates 31 compensate for the difference in thickness. Of course it is to be understood that when this takes place the clip 32 hereinafter described willrbe removed.

When the marker is used upon flat work such as liat sheets the strips 31 are fixed relative to each other by a clip 32 engaging both strips. A suitably located spring 33 may be used to hold the marker in engagement with the sheet and to facilitate this action the arms areconstructed to have a. locking. engagement with each other and the base as illustrated at 34 in Figs. 13, 14 and 15.

In Figs. 5 and 6 I have illustrated one form of feed mechanism for driving the drum 11 which consists of a manually operated lever 35 pivotally connected to the base as illustrated at 36 with its short arm connected to a dog 37 acting upon the ratchet 38 secured to the drum 11. This ratchet is held against backward movement by a pawl 39 that has an extension 40 arranged to be engaged by the finger 41 on the lever when the-latter has been thrown to its eXtreme position. in one direction with the result'that the pawl 39 is released from the ratchet for allowing free movement of the drum A yspring 42 is arranged to return the lever 35 to its normal position after each operation.

From the foregoing description it will be seen that uponmanipulating thel lever 35 the drum 11 will be rotated for taking up the flexible elements 10 which owing tothe connection with the spools m'ovethe rollers toward each other. Movement ,of the rollers toward each othercauses the frame F to be extended and as the drum ismoved step by step. the frame' will be extended stepV by step.

the distance of each step corresponding to the spacing of the lines of` printed matter. l/Vhen it is necessary to collapse the frame to its original position it is only necessary to'move the lever 35 to one of its eXtreme positions which causes the finger 41 to depress the pawl 39 and allow the drum 11 free movement. The weight of the frai'ne will cause the same to collapse to its original position which is reachedy when the spools 7 engage the shoe 18. When it is necessary to fully collapse the frame the trip device 19 is operated which allows the shoes 18 to move out of engagement with the spools 7 and allows greater travel of the rollers.

To complete the invention I provide a regulating device 43 for regulating the distance of travel of the lever 35 so that different spaces may accommodated. In this particular instance the regulating device consists ofan adjustable stop 44 arranged in the path of movement of the lever and having screw threaded engagement with an indicator 45 slidably mounted in the slot 46 in the base and coperating with a scale 47. If found advantageous in practice a curtain 48 may be provided for covering the frame and this curtain has one end wrapped around a spring roller 49 while the other end is secured to the member 22 as indicated It is to be understood that while all of the several features ofv my improved copy holder have special coperation with one another and together constitute a particularly effective mechanism for the purpose in view, certain of these features may be applied in other relations, and I thereforedesire to cover the combinations present in the several lparts of my improved copy holder whet er employed in the general organization shown or elsewhere.

It is further to be understood that the structural embodiment of the invention as a whole and its various features as shown is merely illustrative and not restrictive since I am well aware that many of the details of construction can be widely varied without departing' from the spiritV of the invention. I therefore do not desire toA be limited in these particulars or in any others, except asset forth in the appended claims.
